Glycan signature (A) Heat map and hierarchical clustering of lectins. The hiPSCs and parental SCs are depicted by colored bars (red, SCs; purple, hiPSCs). (B) Correspondence between lectin gene expression patterns and glycan signatures. The lectin-glycosyltransferase relationships are described, together with their reactions. The lectins were selected under the condition that the corresponding glycosyltransferases were found in the expression signature.
